Baltic Birch Plywood Technical Specifications
Face Grade Description
Grade “B”
Single piece veneer of light and uniform colour. A few small pin knots and some brown streaks are allowed. Veneer of this grade is intended for natural finishes. Patches are not allowed. The majority of Grade B veneers are the equivalent of the American “white birch” faces.
Grade “BB”
Single piece face has light and uniform colour. A few sound tight knots and pin holes are permitted. Open knots and defects are replaced with small oval or round veneer patches before gluing. The patches are selected to closely match the background colour.
Grade “CP”
Single piece face is very close to Grade BB in quality. Thin splits are allowed. The oval or round patch may have a different colour from the background.
Grade “C”
Open defects such as open knots and veneer splits are allowed. Sanding is not required. Recommended for the building of containers and dust panels; can be used for crating and in manufacturing, where construction and strength are more important than the appearance.
